- /* FT_VALIDATE_TIGHT :: */

- /* don't have incorrect values, etc. */

- /* FT_VALIDATE_PARANOID :: */
- /* Only for font debugging. Checks that a table follows the */
- /* specification by 100%. Very few fonts will be able to pass this */
- /* level anyway but it can be useful for certain tools like font */
- /* editors/converters. */
